Subordinate Functional Battalions
The COSCOM attaches functional battalions to the rear CSG to perform corpswide GS support missions, reinforce the forward CSGs, and support surges in corps operations. The number and type of functional battalions attached to the rear CSG vary based on requirements, METT-T, and the existence of equivalent HNS ammunition, petroleum, and transportation organizations.
This chapter covers the organizational composition of each type of functional battalion. Both H and L-series companies may be assigned or attached to these battalions. As a result, CSGs and subordinate battalion staffs could control and provide technical supervision of a mix of units organized under both H and L TOEs.
Normally, an S&S battalion is attached to the rear CSG to provide GS level supply (less medical, ammunition, and bulk fuel) and primary field services (mortuary affairs and airdrop) to nondivision units, divisions, separate brigades, and ACRs.
The HHD, Supply and Service Battalion (TOE 42446L000), commands and controls attached GS level supply, mortuary affairs, and airdrop support companies. The battalion headquarters--
- Provides command, control, staff planning, and technical supervision for two to five companies that provide GS level supply and primary field services.
- Exercises technical supervision over mission operations of subordinate units, except for those supply control functions provided by the CMMC.
- Provides technical staff supervision of unit level supply and maintenance operations of subordinate units.
- Provides supervision for administration, training, and operations.
The rear CSG commander task organizes the S&S battalion to meet the requirements of METT-T. Figure 5-1 depicts units which can be attached to an S&S battalion. Both H and L series TOE units may be assigned or attached. DS supply companies and field services companies are attached to CSBs, The battalion organization depends on the size of the corps (soldiers supported), planning factors, and work load.
A battalion headquarters is allocated for two to five subordinate units. Allocation of subordinate units depends on requirements and stated capabilities. However, for planning purposes the --
- GS supply company allocation is one company per TOE capability to receive, store, and issue 467 STONs per day of Class I, II, packaged III, and IV.
- Heavy materiel supply company allocation is one company per TOE capability to receive, store, and issue 1,400 STONs of Class VII per day as well as deprocess approximately 280 STONs of Class VII supplies.
- Repair parts supply company allocation is based on TOE Level I capability to receive, store, and issue 102 STONs of Class IX repair parts. At TOE Level I, it maintains a 15-day stock of Class IX non-ALOC supplies and a 30-day supply of maintenance related Class II and Class IX ALOC supplies, for a maximum of 20,000 ASL line items.
- Light airdrop supply company initial allocation is one per corps.
- Airdrop equipment repair and supply company is allocated on the basis of one per airdrop supply company and one per airborne division.
- Collection company is allocated on the basis of one company per corps.
Subordinate units provide corpswide support. Units normally locate in the rear of the corps rear area, within easy access to MSRs, rail, or airfields.
Only one ammunition battalion is required per COSCOM to support a fully deployed corps. The conventional ammunition ordnance battalion is attached to the rear CSG to establish and operate ammunition supply facilities. This battalion provides corpswide GS ammunition support to divisions, separate brigades, and ACRs.
The HHC, Ordnance Battalion, Conventional Ammunition (TOE 09466L000), provides --
- Command, control, and staff planning for up to five subordinate units.
- Technical direction over the mission operations of subordinate units (except for the supply and maintenance management functions for which the CMMC is responsible).
Figure 5-2 depicts the organization of a conventional ammunition battalion. The number of GS ammunition units attached to the battalion depend upon the --
- Tactical situation.
- COSCOM stockage objectives.
- Existing HNS organization.
- Transportation assets and effectiveness of throughput from the COMMZ.
- Type and density of weapons supported.
- Projected intensity of battle and ammunition consumption rates.
An ammunition battalion HHC is allocated per two to five companies commanded. Allocation of ammunition companies depends on the --
- Number of lifts needed to move the required ammunition tonnage from the time of its arrival in the corps rear area until its issue from the ASPS or ATPs.
- Estimated percentage of ammunition tonnage that can be throughput.
Mission requirements may necessitate attaching conventional ammunition supply and maintenance teams (TOE 09530H4) to augment company-size units in the area of ammunition supply, maintenance, and munitions safety control.
GS conventional ammunition units set up a corps storage area in the corps rear area. A CSA is required for each committed division to support ASP and ATP issue operations. Corps truck units provide transportation support.
The petroleum supply battalion is assigned or attached to the rear CSG for command and control. This battalion provides corpswide GS bulk fuel support for nondivision DS supply units, divisions, separate brigades, and ACRs.
The HHD, Petroleum Supply Battalion (TOE 10426L000), provides command and control and administrative, technical, and operational supervision over assigned or attached petroleum supply companies, transportation medium truck companies (petroleum), and a mobile petroleum products laboratory team. The headquarters staff --
- Supervises the command's petroleum quality surveillance program.
- Plans for the storage, distribution, and quality surveillance of bulk petroleum products required by division and nondivision DS units in the corps area.
- Ensures that attached petroleum supply units maintain a prescribed portion of the corps petroleum reserve.
Figure 5-3 depicts the variable organization of a petroleum supply battalion. The battalion organization depends upon the --
- Type and level of conflict.
- Availability of bulk petroleum in underdeveloped theaters.
- Availability of HN units.
- Consumption of bulk fuel.
- Requirement for petroleum quality surveillance.
Only one petroleum supply battalion is required per COSCOM to support a fully deployed corps. The battalion HHD is allocated per two to six petroleum supply companies and transportation medium truck companies (petroleum).
The COSCOM allocates petroleum supply companies on the basis of --
- One petroleum supply company per armor or mechanized division.
- One petroleum supply company (TOE 10427L000) per two airborne, air assault, or infantry divisions or combinations thereof. Allocation of petroleum supply companies (TOE 10227H500) is based on one company per 685,000 gallon daily requirement.
A petroleum supply company should not support more than one division slice of the corps. Allocation depends on the size of the corps reserve and daily consumption. For example, two or three petroleum supply companies may be needed to support the daily consumption requirements of a mechanized heavy corps.
The COSCOM allocates transportation medium truck companies (petroleum) per stated mission capabilities. Resupply routes to supported units may approximate 60 miles round trip, given two round trips per shift or four trips per day. Allocation needs to be modified to adjust to the corps commander's plan, priorities established by the CMMC's bulk fuel commodity managers, road conditions, and throughput distances.
The CMCC commits tractors assigned to transportation medium truck companies (petroleum) which are not supporting petroleum distribution requirements to other line haul transportation support missions.
If required, the COSCOM allocates a mobile petroleum laboratory team to a CSG. Requirements depend on --
- Testing requirements (accelerated in hot climates).
- Criticality of the fuel.
- Intended use of the fuel.
- Type of theater (developed or undeveloped).
Units provide corpswide support. Subordinate petroleum supply companies and supporting truck companics (petroleum) normally employ in the rear of the corps rear area near a hard surface MSR on level, well-drained terrain. They often employ near a railhead or seaport.
If the aircraft density in the corps area requires more than one AVIM unit, an aviation battalion (AVIM) is required. The battalion is then attached to the rear CSG.
The HHD, Aviation Battalion (AVIM) (TOE 01946L000) --
- Provides command and control for attached units.
- Operates the battalion communications net, both wire and radio.
- Provides unit level maintenance of CE equipment for subordinate units.
- Provides staff planning, implementation, and execution in support of the battalion maintenance mission.
- Provides aviation maintenance and supply operations program direction to assigned, attached, or OPCON units.
- Provides unit level administration to the elements of the battalion.
The AVIM battalion consists of a variable number of aviation companies (AVIM). Figure 5-4 depicts the battalion organization.
The COSCOM bases allocation on the density of aircraft supported. Allocation of AVIM units depends on the number of aircraft in the corps supported.
AVIM units support on an area basis. They provide AVIM and aviation repair parts support to nondivision units within the corps area. As necessary, AVIM units provide direct support to ACRs. When the work load for division AVIM units in the DSA becomes too great the work load is passed back to corps AVIM units. Heavy division AVIM platoons may passback 25 percent of their work load to the supporting corps AVIM unit. Even higher percentages of passback may require that corps AVIM units be augmented when tasked to support light infantry division units. The aviation battalion manages the cross-leveling of work loads between its AVIM units.
The COSCOM can attach a transportation battalion to the rear CSG. This battalion provides corpswide transportation support. It throughput GS supplies from the rear CSG to the division area and backs up movement of supplies from forward CSGs. The battalion supports evacuation missions. It also moves units, supporting division moves.
The HHD, Transportation Motor Transport Battalion (TOE 55716L000) --
- Provides command supervision for three to eight transportation companies and attached supporting units.
- Supervises the operation of truck terminals, trailer transfer points, or a trailer relay system when required and augmented by motor transport teams.
- Receives and translates transport requirements from the supporting MCT or CMCC into specific vehicle commitments and assigns these commitments to subordinate truck units.
- Evaluates highway traffic circulation plans to determine best routing.
- Plans and schedules tasks for subordinate units to conform with the overall movements program and with operating requirements and capabilities.
- Provides unit maintenance on communications electronic equipment for attached units. It depends upon one of its attached companies for unit maintenance for wheeled vehicle and power generation equipment.
Figure 5-5 depicts the variable organization of a transportation battalion. The battalion may consist of a mix of medium, combat HET companies, and cargo transfer companies. The battalion organization depends upon --
- Requirements for truck transport.
- Availability of HN truck companies or assets.
- Availability of other transport modes.
- Condition of road networks.
- Distances to supported units.
The basis of allocation for a transportation battalion HHD is one per three to eight subordinate motor transport operating companies or equivalent units. Allocation of subordinate units depends upon local and line-haul capabilities of truck units and requirements to operate terminals and tranship cargo.
Truck companies assigned to the transportation battalion provide support on a corpswide basis. Medium truck companies line-haul cargo from the rear of the corps rear area to the DSA/BSA. Combat HET companies haul tracked vehicles during relocation of a brigade task force. Cargo transfer companies transship cargo at arrival airfields, marshaling area, forward mode transfer points, and rail terminals.
To meet mission requirements for potable water in hot, arid environments, the COSCOM assigns or attaches a water supply battalion to the rear CSG. Subordinate units purify, store, and distribute potable water. For contingency operations, subordinate units can be attached to a forward CSG. For example, water purification detachments and teams can be attached to augment the water purification capability organic to DS supply companies.
The HHD, Water Supply Battalion (TOE 10466L000) provides command, administrative, technical, and organizational control over two to six assigned or attached water supply companies or company equivalents engaged in providing potable water support. The battalion HHD --
- Plans and supervises the supply of potable water.
- Exercises control over the supply of potable water through the water supply branch.
- Provides technical and operational supervision for water purification, supply, and distribution.
- Plans, controls, and supervises battalion employment, deployment, security, and operations.
- Provides unit maintenance on organic communications equipment and communications-electronic equipment organic to assigned or attached units. A water supply company provides unit maintenance support for the battalion HHD.
Figure 5-6 depicts the variable organization of a water supply battalion. The actual organization depends upon the--
- Climate and geographic area of employment.
- Size of the force to be supported.
- Number of troops supported.
- MOPP level and decontamination required.
- Theater shower policy.
Water supply companies establish and operate up to eight DS water issue points in support of division and nondivision units in an arid environment. They set up 50,000-gallon collapsible water storage bags and operate tactical water distribution systems. Augmentation of TWDS teams extends the TWDS to 80 miles.
Water purification detachments operate ROWPUs at up to five locations. A barge mounted ROWPU team produces potable water from salt or freshwater sources. Water purification teams operate four water points to produce potable water using a fresh water source.
Transportation medium truck companies transport potable water using 4,750-gallon fabric collapsible tanks mounted on semitrailers.
A water supply battalion HHD is allocated on the basis of one per two to six subordinate units required to provide potable water support. Allocation of subordinate units is based on TOE mission capabilities.
Though water purification detachments normally operate out of base terminals, they may locate near any large water source. TWDS and water storage distribution sets require special transport. Once base terminals, storage tank farms, and TWDS are emplaced, truck companies haul semitrailer mounted fabric tanks of potable water from corps area tank farms forward to division and brigade storage facilities. Supported units pick up water from storage and distribution points using tank trucks, water trailers, or 5-gallon water cans.
